Hi — I'm Ash.
I teach domain experts to validate startup ideas in 90 days using AI.

In 2009, I had an epiphany: Life's Too Short to Build Something Nobody Wants.

I had launched dozens of products by then, but something bothered me. While all my ideas started off as awesome ideas, not all of them ended up as awesome products. I didn't have a repeatable process for systematically navigating the highly uncertain terrain of early-stage products.

This sparked my search for a better and faster way for building successful products which first led me to the early works of Eric Ries and Steve Blank who pioneered the Lean Startup movement. I joined in on the conversation and began rigorously testing and applying these principles to my products.

This tinkering led to the development of several business modeling tools (Lean Canvas, Traction Roadmap, and the Customer Forces Canvas), two best-selling books (Running Lean and Scaling Lean), and a series of step-by-step playbooks for building and launching products (Continuous Innovation Framework). Today, over 10 million people have used these tools across startups, accelerators, and universities in 100+ countries.

But something has changed. AI collapsed the cost of building by 98%. A solo founder in 2026 can run a technology stack that would have cost $15K/month in salaries two years ago — for under $200/month. The execution barrier is gone. But the cost of building the wrong thing stayed exactly the same.

That's why I'm building LEANSpark — an AI co-founder that guides domain experts through 90-day validation cycles. Lean Canvas, customer interviews, Demo-Sell-Build, first revenue. It's the only AI tool built by the person who invented the methodology.

I believe the biggest untapped founder pool isn't in Silicon Valley. It's domain experts sitting inside companies, solving hard problems every day, who don't know the startup playbook yet. AI handles the build. Lean methodology provides the validation. Domain expertise provides the direction. I call this the 100X Founder.
